Outline of Final Research Achievements

This study has proposed and developed the floating/submerged tsunami shelter to evacuate huge tsunami attacking and then has also investigated tsunami force acting on the shelter and its motions caused by tsunami impact force in particle based method and experimental work. The main results can be summarized as follows. The ellipsoidal tsunami shelter (E35s type) can drastically reduce tsunami force and impact pressure. Moreover the surge and yaw motions in E35s with mooring system type can be also reduced comparing with Box type. In further research, the tsunami tower building with opening parts and piloti is also useful as one of tsunami evacuating options. The tsunami shelter and tower building should be arranged to reduce unpredictable tsunami force caused by a surrounding building and accommodation.
